Blast furnaces extract pure iron from the iron(III) oxide in iron ore in a two step sequence.In the first step, carbon and oxyge
Alona [7]

Answer:

The net chemical equation for the production of iron from carbon, oxygen and iron(III) oxide:

2Fe_2O_3 (s) +6C (s) + 3O_2 (g)\rightarrow 4Fe (s) + 6CO_2 (g)

Explanation:

Step 1: Carbon and oxygen react to form carbon monoxide:

2C (s) + O_2 (g)\rightarrow 2CO (g)..[1]

Step 2: Iron(III) oxide and carbon monoxide react to form iron and carbon dioxide:

Fe_2O_3 (s) + 3CO (g)\rightarrow 2Fe (s) + 3CO_2 (g)..[2]

The net chemical equation for the production of iron from carbon, oxygen and iron(III) oxide can be obtained by :

3 × [1] + 2 × [2]

2Fe_2O_3 (s) + 6CO (g)+6C (s) + 3O_2 (g)\rightarrow 4Fe (s) + 6CO_2 (g)+6CO(g)

CO gas will gas cancel out form both sides ans we will get the net chemical equation:

2Fe_2O_3 (s) +6C (s) + 3O_2 (g)\rightarrow 4Fe (s) + 6CO_2 (g)

According to reaction, 2 moles of ferric oxide reacts with 6 moles of carbon and 3 moles of oxygen gas to give 4 moles of iron and 6 moles pf carbon dioxide gas.
